How to Use the Shoe Size Converter?

To convert shoe sizes between different regions, select your gender, choose the region system you're converting from (US, UK, EU, China, Japan, Korea, Mexico, Australia, Brazil, Russia, or India), enter your shoe size, and click Convert. The tool will instantly display the equivalent sizes in all major regional sizing systems in a convenient table format.

This converter uses standardized conversion formulas based on foot length measurements. Keep in mind that actual sizes may vary slightly between brands and manufacturers, so it's always recommended to try on shoes when possible.

Shoe Size Conversion Principles

1. Foot Length Measurement

All shoe size conversions are based on the actual foot length in centimeters or inches. Different regional sizing systems use different formulas to convert foot length to size numbers.

2. Gender Differences

Men's, women's, and children's shoe sizes use different conversion formulas. Women's sizes are typically 1.5-2 sizes larger than men's for the same foot length in US sizing, while other regions may use different scales.

3. Regional Standards

• US sizing: Uses numbers with half sizes, different scales for men and women
• UK sizing: Similar to US but typically 1 size smaller
• EU sizing: Based on Paris Points (2/3 cm), unisex scale
• China sizing: Uses foot length in millimeters
• Japan sizing: Uses foot length in centimeters
• Korea sizing: Uses foot length in millimeters (mm)
• Mexico sizing: Similar to US sizing
• Australia sizing: Same as UK sizing
• Brazil sizing: Uses foot length in centimeters with different scale
• Russia sizing: Based on foot length in centimeters, similar to EU but different numbering
• India sizing: Typically same as UK sizing

4. Mathematical Conversion

The conversion process typically involves: (1) Converting the input size to foot length, (2) Converting foot length to the target regional size using that region's formula.

5. Half Sizes

Some regions (like US and UK) use half sizes (e.g., 8.5), while others (like EU and Asian sizes) typically use whole numbers only. The converter handles these differences automatically.

6. Brand Variations

Keep in mind that actual shoe sizes can vary between brands and manufacturers. These conversions are based on standard measurements, but you should always try shoes on when possible or check the brand's specific size chart.
